The y-axis is not suitably scaled to effectively view the pink curve.
If we "stretch" it, you'd more easily see that the local maximum (turning point) of the pink graph
occurs at the exact same x which locates the minimum value (turning point) of the U-shaped parabola.

If you invert a quadratic equation, the zeros go towards infinity (become vertical asymptotes),
local maxima become local minima and local minima become local maxima.
